Immunity (medical)

immunityimmuneimmune response
Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides.
Adaptive immunity can also be divided by the type of immune mediators involved; humoral immunity is the aspect of immunity that is mediated by secreted antibodies, whereas cell mediated immunity involves T-lymphocytes alone.

Cell-mediated immunity

cellular immunitycell-mediatedcellular immune response
It contrasts with cell-mediated immunity. The study of the molecular and cellular components that form the immune system, including their function and interaction, is the central science of immunology.
Historically, the immune system was separated into two branches: humoral immunity, for which the protective function of immunization could be found in the humor (cell-free bodily fluid or serum) and cellular immunity, for which the protective function of immunization was associated with cells.

Immune system

The study of the molecular and cellular components that form the immune system, including their function and interaction, is the central science of immunology.
In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity.

The study of the molecular and cellular components that form the immune system, including their function and interaction, is the central science of immunology.
The latter is further divided into humoral (or antibody) and cell-mediated components.

Cytokine

cytokineschemical signalsinflammatory chemical signals
Humoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.
They act through receptors, and are especially important in the immune system; cytokines modulate the balance between humoral and cell-based immune responses, and they regulate the maturation, growth, and responsiveness of particular cell populations.

Adaptive immune system

adaptive immunityadaptive immune responseadaptive
The immune system is divided into a more primitive innate immune system, and acquired or adaptive immune system of vertebrates, each of which contains humoral and cellular components.
Like the innate system, the acquired system includes both humoral immunity components and cell-mediated immunity components.

Germinal center

germinal centregerminal centersgerminal centres
Humoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.
Germinal centers are an important part of the B cell humoral immune response, acting as central factories for the generation of affinity matured B cells specialized in producing improved antibodies that effectively recognize infectious agents, and for the production of durable memory B cells.

B cell

BB lymphocytesB-cell
In humoral immune response, first the B cells mature in the bone marrow and gain B-cell receptors (BCR's) which are displayed in large number on the cell surface.
They function in the humoral immunity component of the adaptive immune system by secreting antibodies.

Antibody

Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides.
The production of antibodies is the main function of the humoral immune system.

T helper cell

Humoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.

Passive immunity

Passive immunity is the transfer of active humoral immunity of ready-made antibodies.

Humorism

humorshumoursfour humours
Humoral immunity is so named because it involves substances found in the humors, or body fluids.
For example, modern medicine refers to humoral immunity or humoral regulation when describing substances such as hormones and antibodies that circulate throughout the body.

Polyclonal B cell response

Polyclonal response
The immune system may respond in multiple ways to an antigen; a key feature of this response is the production of antibodies by B cells (or B lymphocytes) involving an arm of the immune system known as humoral immunity.

Virus

virusesviralvirion
By binding their specific antigens, antibodies can cause agglutination and precipitation of antibody-antigen products, prime for phagocytosis by macrophages and other cells, block viral receptors, and stimulate other immune responses, such as the complement pathway.
This is called humoral immunity.
